FIG. 2

IN VEN TOR Gc'l'nler PRACHT y his ATTORNEYS APPARATUS FOR THE CARE OF THE BODY BACKGROUND OF THE INVENTION This invention relates to an apparatus for the care of the body.

Appliances of this kind are mainly used for callous cutters and are known in a variety of versions. All of them, however, suffer from the major drawback that they only enable a draw cut, rather than a peeling action, to be applied to the callosity of the skin. It has been found in practice, however, that it is more frequently convenient, particularly for a user wishing to remove callouses from his own skin, but for the chiropodist likewise, to peel the callous off, rather than to remove it by a draw cut action. It is true that appliances are already known that enable the callous to be peeled. But these, in turn, do not enable a draw cut action to be effected if desired.

SUMMARY OF THE INVENTION It is, therefore, the object of the present invention to improve on the prior art, in such a way that the callouses can be removed not only in the conventional manner, by a draw cut, but also by a peeling action, if desired. To attain this object the present invention provides an apparatus for the care of the body which comprises an elongated handle; a protective plate carried by one end of the elongated handle and provided with a first slit and a second slit. The first slit extends transversely to the longitudinal axis of the apparatus and possesses at least one exposed tongue. The second slit is situated on the longitudinal axis of the apparatus, intersecting the first slit and also possesses at least one exposed tongue which extends at right angles to the tongue of the first slit. The protective plate is further provided with two planing holes extending at right angles with respect to each other; and a cover plate provided, to enable it to be locked to the protective plate, with a bent-up tab which has at least one slit which serves for the reception of the elongated slot of a replaceable blade. The tab of the cover plate is adapted alternatively to be passed through one of the slits in the protective plate whereby the exposed tongue firmly engages the slit in the tab to clamp the blade.

If callouses are to be peeled off with this apparatus, after it has first been used for the application of a draw cut to the callosity, all that is necessary is to reposition the cover plate and the blade by an angle of 90 with respect to the protective plate. The bent-up tab of the cover plate will then pass through the slit situated in the longitudinal axis of the protective plate of the apparatus and become locked to this latter plate as a result of the fact that its exposed tongue engages the slit of the tab of the cover plate.

The invention also resides in the fact that the protective plate and the cover plate of the apparatus are of the shape of a spherical segment.

This construction for the protective plate and the cover plate of the apparatus ensures that the blade, no matter whether its cutting edge is situated in the zone of one planing hole or of the other planing hole of the protective plate, can be clamped in a curved position, in the manner already known.

According to a further proposal covered by the invention, each slit of the protective plate of the apparatus is provided with two exposed tongues which correspond to slits belonging to the tab of the cover plate and which are situated close to the ends of each slit of the protective plate.

This ensures that after two tongues of the protective plate have engaged the slits of the tab of the cover plate, the entire length of this latter will rest against the protective plate, with an even tractive force.

BRIEF DESCRIPTION OF THE DRAWING FIG. 3 is a plan view of the cover plate of the apparatus, and FIG. 4 is a side view thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENT The apparatus shown in the drawing consists of a protective plate 1 with an elongated handle 2 and a cover plate 3, a twoedged blade 4 of the flat type being clamped between said cover plate 3 and said protective plate 1. The protective plate 1 is provided with a planing hole 5, one cutting edge of the blade 4 being situated in the zone of said hole, and also with a slit 6 positioned transversely to the longitudinal axis of the apparatus. The slit 6 is provided, on one of its longitudinal edges, in the vicinity of each of its ends, with a tongue 7 cut out of the material so as to occupy an exposed self-supporting position. The cover plate 3 is provided with a bent-up tab 8 which properly positions the blade 4. The tab 8 is provided with two slits 9 which correspond to the tongues 7 of the protective plate 1 and which can be engaged by said tongues 7 in order to lock the protective plate 1 to the cover plate 3.

The protective plate 1 is provided with a second slit 10 which is situated on the longitudinal axis of the apparatus and intersects the slit 6, two exposed tongues 11, formed by being cut out of the material and situated at right angles to the tongue 7, being likewise provided on one longitudinal edge of the said second slit l0 and in the vicinity of its respective ends. After the cover plate 3 with the blade 4 has been repositioned by an angle of and after the tab 8 of the said cover plate 3 has passed through the slit 10 of the protective plate I, the tongues 11 of the latter engage the slits 9 of the tab 8 of the cover plate 3, in order to enable the cover plate 3 to be locked to the protective plate 1. One of the cutting edges of the blade 4 is thereafter situated in the zone of a second planing hole 12 which is provided in the protective plate 1 and which is situated at right angles to the planing hole 5. The apparatus can now be used for the removal of the callous by a peeling action. According to a further characteristic of the invention, the protective plate 1 and the cover plate 3 have the shape of a spherical segment, enabling the blade 4 to be clamped in a curved position, no matter what position it occupies in relation to the protective plate 1 and the cover plate 3.

It is naturally within the scope of the invention for a third planing hole to be provided, situated opposite the planing hole 12, thus enabling a peeling action to be carried out with the apparatus by a left-handed person likewise.
